Yeah, sound like you're after competitive shooters, so I'd say you'd want to start with the top eSports in that branch.
Overwatch, in particular, unsurprisingly, integrates a large number of the mechanics to which you're accustomed (dots/hots/burst/cooldowns and other strategic elements of team cycling/synergy) with the more traditional competitive aspects of FPS:
- CS:GO
- Overwatch
- Call of Duty: WWII
- Crossfire
- H1Z1
- Quake: Champions
Not sure if you've seen any of the threads about
Escape from Tarkov, but that game seems to be winning over a lot of the hardcores who gravitate towards not just the "twitch" style of shooters, such as
MOHAA or the
Battlefield series, but those which also attempt to simulate greater realism of firearm and physics reproduction. That game seems to be doing better than any other with the remnants of this audience outside of
PUBG which is devouring pretty much everything. A friend of mine who is an RL badass (but casually games) hit me up about it over a year ago or so, and I shit on it, basically, telling him to keep his hopes down on the grounds that it was being developed by Russians, and how despite their reputation in the cybersecurity sector, they've basically never produced a videogame worth shit. I've been eating my words.
A similar game tracking well right now, though not an eSport, which also integrates aspects of survivalism, like you'd find in the
Fallout series, but with real people (other online gamers) as your adversaries and allies, not bots, is
Rust.
You might also consider the main competitor to
PUBG, and the third most popular game in the world right now, behind
League of Legends and
PUBG: Fortnite. Not sure how you feel about third person in shooters, but it's probably a more intuitive perspective to you considering your
WoW experience. It even boasts cross-platform play between the PS4 and PC crowds. The "Battle Royale" mode, in particular, is the popular one.
The one MOBA-type game you might try out is
Smite, but if you hate the game style I doubt it will be for you. It basically puts you in the first-person perspective of the hero you play, instead of giving you the God's Eye view of the map, and shifts you into an FPS mode of shooter-style controls rather than the point-and-click style more suited to the traditional view.
Other than that:
Rocket League.
*Edit* Oh yeah, lest we forget the biggest F2P PC gaming phenomenon of 2016:
